Using the existing Trend XNC220 platform, Synapsys Solutions has greatly enhanced the firmware of the unit by creating our own variant, the SXNC. Having a much bigger module count (eg: 200 sensors, 1000 digital inputs etc.) and allowing routines to be programmed in C, interfacing options to LON and other sophisticated protocols were possible. The SXNC was the mainstay Trend interfacing product until the release of the IQ3/XNC.
